Will be applied effectively.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is a diagram illustrating a smart key system for effectively dividing an operation region according to an exemplary embodiment of the present invention.

As shown in FIG. 1, a smart key system for effectively dividing an operation region according to the present invention includes a plurality of smart key interface units installed in each of the plurality of smart key operation regions, and provides a predetermined smart key from a user. When requesting a function operation, a non-response command is transmitted through the corresponding smart key interface unit of the smart key operation region corresponding to the smart key function in response to the smart key function, and a smart key search command according to the smart key function is executed through the remaining smart key interface unit. The immobilizer unit 60 to transmit and the smart key 10 which do not respond in response to the smart key search command received from the immobilizer unit 60 when a non-response command is received from the immobilizer unit 60 are included.

The smart key 10 receives and stores a smart key number as its own authentication information, and accesses the immobilizer unit 60 within a predetermined proximity distance to the smart key search command transmitted from the immobilizer unit 60. In response, the smart key number is transmitted to the immobilizer unit 60 as its authentication information.

When the smart key 10 receives the non-response command transmitted from the immobilizer unit 60 by approaching the immobilizer unit 60 within a predetermined proximity distance, the smart key search command received from the immobilizer unit 60 afterwards. Does not respond in response. That is, when the smart key 10 receives the non-response command from the immobilizer unit 60, the smart key 10 does not respond to the received smart key search command for searching the smart key later.

At this time, when the non-response command is received from the immobilizer unit 60, the smart key 10 corresponds to the smart key search command received from the immobilizer unit 60 for a predetermined non-response setting time after receiving the non-response command. If the smart key search command is received from the immobilizer unit 60 after the non-response set time has elapsed, it is preferable to respond to this and transmit the smart key number to the immobilizer unit 60 as its own authentication information. Do.

The immobilizer unit 60 stores the user authentication information including the smart key number of the registered smart key as a valid key, searches for the presence of a smart key approaching within a predetermined proximity distance, and then accesses within the proximity distance. When is searched, the smart key number received from the smart key is compared with a valid smart key number of pre-stored user authentication information, and if the approached smart key is determined to be a valid smart key, it operates with a preset smart key function.

When the immobilizer unit 60 searches for the presence of a smart key approaching within a close distance, the mobile device 60 does not respond through the corresponding smart key interface unit of the smart key operating area corresponding to the excluded operation area in response to the requested smart key function. Send a command, and then send a smart key search command according to the smart key function through the remaining smart key interface unit.

Hereinafter, the immobilizer unit 60 will be described in more detail.

The immobilizer unit 60 is provided in each of a plurality of smart key operating regions and an authentication information storage unit 40 for storing user authentication information including a smart key number of a pre-registered valid smart key, and a predetermined proximity distance. Pre-stores smart key operation area information corresponding to a plurality of smart key interface units 52, 54, 56 communicating with a smart key located within and at least one operation-excluded area corresponding to each of at least one smart key function If an operation of a predetermined smart key function is requested from the user, a non-response command is transmitted through the corresponding smart key interface unit of the smart key operation area corresponding to the requested operation exclusion area. Immobilizer control unit 30 for transmitting a smart key search command according to the smart key function requested through the remaining smart key interface unit; It should.

The authentication information storage unit 40 pre-stores user authentication information including a unique smart key number of a smart key (for example, smart key 10) registered as a valid key. That is, the authentication information storage unit 40 stores the pre-registered smart key number as valid user authentication information required for authenticating a valid smart key.

A plurality of smart key interface units 52, 54, 56 are provided in each of the smart key operating regions in the vehicle 100. In the smart key system of the present invention, when three smart key interface units are included in the immobilizer unit 60, as shown in FIG. 3, the first operation corresponding to the front seat including the driver's seat in the vehicle 100 is illustrated. The first smart key interface unit 52 is installed in the region 130, and the second smart key interface unit 54 is installed in the second operation region 150 corresponding to the rear seat in the vehicle 100. The third smart key interface unit 56 may be installed in the third operation region 170 corresponding to the trunk of 100.

As such, the plurality of first, second, and third smart key interface units 52, 54, and 56 installed in the first, second, and third operating regions respectively assigned to the smarts are located within a predetermined proximity distance. Antennas 53, 55, and 57 may be included to interface via key and wireless communication.

The immobilizer control unit 30 searches whether a smart key approaching within a predetermined proximity is present through the plurality of smart key interface units 52, 54, and 56, and when the smart key approaching within the proximity is found, the immobilized controller 30 searches for the smart key. Compare the smart key number received from the valid smart key number of the user authentication information previously stored in the authentication information storage unit 40, and if the approached smart key is determined to be a valid smart key, it operates with a preset smart key function.

The immobilizer control unit 30 preferably stores the smart key operation region information corresponding to the non-operation region previously set corresponding to each of the at least one smart key function. That is, the immobilizer control unit 30 may include at least one smart key function, for example, a door lock / unlock function for automatically locking / unlocking a passenger door of the vehicle 100 and a trunk door of the vehicle 100. Preset operation zones in response to smart key functions such as the trunk door lock / unlock function that automatically locks / unlocks, and the start-on function that automatically turns on the vehicle 100. Pre-stores the smart key operation area information. For example, the third operation region 170 in which the third smart key interface unit 56 is installed is set as the operation exemption area in response to the door lock / unlock function, and the operation exemption is performed in response to the trunk door lock / unlock function. As the area, the first and second operation areas 130 and 150 provided with the first and second smart key interface parts 52 and 54 are set in advance, and the third smart key as the operation exemption area corresponding to the startup ON function. The third operation region 170 in which the interface unit 56 is installed may be preset.

Thus, the immobilizer control unit 30, when a user requests the operation of a predetermined smart key function from the user approaching the vehicle 100, before searching whether there is a smart key approaching within a close distance, the requested smart key function In response to the non-response command is transmitted through the corresponding smart key interface unit of the smart key operation area corresponding to the preset operation exclusion area, and then transmits the smart key search command according to the requested smart key function through the remaining smart key interface unit. do.

For example, when the user requests the operation of the start-on function as the user presses the start button, the immobilizer controller 30 responds to the requested smart key function (start-on function). The non-response command is transmitted through the corresponding smart key interface unit (eg, the third smart key interface unit 56) of the smart key operation region (eg, the third operation region 170) corresponding to the set operation excluded region. Accordingly, a radio signal corresponding to an unresponsive command is transmitted within an adjacent proximity distance through the antenna 57 of the third smart key interface unit 56, and is approached from the antenna 57 of the third smart key interface unit 56. If the smart key 10 is located within a distance, that is, the third operation region 170, the smart key 10 will receive a non-response command.

After transmitting the non-response command through the third smart key interface unit 56, the immobilizer controller 30 transmits the smart key search command through the remaining first and second smart key interface units 52 and 54. FIG. Do it. Of course, after transmitting the non-response command through the third smart key interface unit 56, the immobilizer control unit 30, not only the remaining first and second smart key interface units 52 and 54, but also the third smart key interface unit. The smart key search command can also be transmitted through (56).

Accordingly, the smart key operation region (eg, the third operation region) in which the smart key search command transmitted through the antennas 53 and 54 of the first and second smart key interface units 52 and 54 corresponds to the non-operation region. (170), the smart key 10 that has previously received the non-response command will not respond to the smart key search command.

At this time, the smart key 10 is within a close distance from the antenna 53 of the first smart key interface unit 52, that is, from the antenna 55 of the first operating region 130 or the second smart key interface unit 54. If the smart key 10 receives the smart key search command transmitted through the first smart key interface unit 52 or the second smart key interface unit 54 within a close range, that is, within the second operating area 150. In response, the smart key 10 will transmit its smart key number. Accordingly, when the smart key number received from the smart key 10 is received in response to the smart key search command through the first smart key interface 52 or the second smart key interface 54, the immobilizer controller 30 On the basis of the received smart key number and the user authentication information stored in the authentication information storage unit 40 authenticates whether the smart key 10 is a registered valid smart key.

 Accordingly, when the approaching smart key 10 is determined to be a valid smart key, the immobilizer controller 30 operates with a preset smart key function in response to a request for a start-up function operation from a user. That is, the immobilizer control unit 30 allows the start control device 50 to start the vehicle 100 in response to a request for a start-on function operation from the user.

Here, although the above description has described a case where an operation for starting the ON function from the user is requested, it also operates in response to various smart key functions such as a door lock / unlock function and a trunk door lock / unlock function. Naturally, the present invention can be realized if the exclusion area is set in advance.

In addition, in the above description, the immobilizer unit 60 of the smart key system according to the present invention is described as having three smart key interface units to divide the operation area into three, but this is only one embodiment, a larger number It is natural that the present invention can be realized by bending the smart key interface part of the vehicle and dividing the area of the vehicle 100 into a larger number of operating areas.

As described above, according to the present invention, the smart key system for effectively dividing an operation region includes a smart key 10 approaching within a close distance when an operation of a predetermined smart key function is requested from a user approaching the vehicle 100. ), Before retrieving whether or not), the non-response command is transmitted through the corresponding smart key interface unit of the smart key operation area corresponding to the preset operation exclusion area in response to the requested smart key function, and then requested through the remaining smart key interface unit. The smart key search command according to the smart key function is transmitted.

Accordingly, the smart key system according to the present invention is effectively applied in an operation region in which the wireless command transmitted from the immobilizer unit 60 does not want to be used when the smart key function is operated, i. You can do that.

Hereinafter, with reference to FIG. 2, it will be described in detail the control flow of the operation method of the smart key system for effectively distinguishing the operation area according to an embodiment of the present invention. For convenience of description, the configuration shown in FIG. 1 described above will be described with reference to the corresponding reference numerals.

First, the immobilizer unit 60 included in the present invention includes at least one smart key function, for example, a door lock / unlock function that automatically locks / unlocks a passenger door of the vehicle 100. Corresponds to smart key functions such as trunk door lock / unlock function that automatically locks / unlocks the trunk door, and start-on function that automatically turns on the vehicle 100. Pre-store smart key operation area information that is set as exclusion area. For example, the third operation region 170 in which the third smart key interface unit 56 is installed is set as the operation exemption area in response to the door lock / unlock function, and the operation exemption is performed in response to the trunk door lock / unlock function. As the area, the first and second operation areas 130 and 150 provided with the first and second smart key interface parts 52 and 54 are set in advance, and the third smart key as the operation exemption area corresponding to the startup ON function. The third operation region 170 in which the interface unit 56 is installed may be preset.

Hereinafter, for convenience of description, a description will be made with reference to the start-on function as an example of a smart key function requested to be driven by a user.

When the user approaching the vehicle 100 presses the start button, when the operation of the start-on function is requested from the user (S10), the immobilizer unit 60 corresponds to the requested start-on function. A non-response command is transmitted through the corresponding smart key interface unit (eg, the third smart key interface unit 56) of the smart key operation region (eg, the third operation region 170) corresponding to the preset operation exclusion area ( S20). Thus, if the smart key 10 is located within a close distance from the antenna 57 of the third smart key interface unit 56, that is, the third operating region 170, the smart key 10 will receive a non-response command. will be.

After transmitting the non-response command through the third smart key interface unit 56, the immobilizer unit 60 transmits the smart key search command through the remaining first and second smart key interface units 52 and 54. (S30). Of course, after transmitting the non-response command through the third smart key interface unit 56, the immobilizer unit 60, as well as the remaining first and second smart key interface units 52 and 54, may also be the third smart key interface unit. The smart key search command can also be transmitted via (56).

Accordingly, the smart key 10 is located in any one of the first operation region 130, the second operation region 150, and the third operation region 170 corresponding to the operation region of the smart key function of the vehicle 100. If present, it will receive a smart key search command sent from immobilizer unit 60. Thus, the smart key 10 determines whether the non-response command transmitted from the immobilizer unit 60 has been received (S40). If it is determined that the non-response command has been received, the smart key 10 does not respond in response to the smart key search command sent from the immobilizer unit 60 (90). That is, when the smart key 10 receives the non-response command from the immobilizer unit 60, the smart key 10 does not respond to the received smart key search command for searching the smart key later.

At this time, when the smart key 10 receives a non-response command from the immobilizer unit 60, it is preferable to count a predetermined non-response setting time. Thus, if it is determined that the response response command is received, the smart key 10 determines whether the non-response setting time has elapsed (S80), and if the non-response setting time has not elapsed, the smart key search command received from the immobilizer unit 60. It does not respond in response to (S90). On the other hand, when the non-response setting time has elapsed in S80, the smart key 10 responds normally to the smart key search command received from the immobilizer unit 60 and sends the smart key number as its own authentication information to the immobilizer unit 60. It is preferable to transmit by (S50).

On the other hand, if it is determined in step S40 that the smart key 10 has not received a non-response command from the immobilizer unit 60, in response to the smart key search command received from the immobilizer unit 60 responds normally as its own authentication information The smart key number is transmitted to the immobilizer unit 60 (S50).

Accordingly, when a smart key number received from the smart key 10 is received in response to the smart key search command, the immobilizer unit 60 receives the smart key 10 based on the received smart key number and pre-stored user authentication information. The authentication determines whether the registered smart key is valid (S50).

Therefore, the smart key system for effectively classifying the operating area according to the present invention is used in the operating area that does not want to use the wireless command transmitted from the immobilizer unit 60, that is, the operation exclusion area when the smart key function is operated. It can be effectively applied in the desired operating area.

Although the present invention has been described in detail with reference to preferred embodiments, the present invention is not limited to the above-described embodiments, and the technical field to which the present invention belongs without departing from the gist of the present invention as claimed in the following claims. Anyone skilled in the art will have the technical idea of the present invention to the extent that various changes or modifications can be made.

When an operation of a predetermined smart key function is requested from a user approaching the vehicle, a non-response command is first transmitted to a preset operation exclusion area in response to the requested smart key function, and then the smart key according to the requested smart key function. By applying a search command, the smart key system can be applied effectively in the operating area where the wireless command transmitted from the immobilizer unit does not want to be used during operation of the smart key function, that is, not in the non-operating area. In this case, it is possible to make a great progress in terms of efficiency of driver area division and increase of driver's convenience according to the smart key function, and there is not only enough possibility of marketing or sales of the applied smart key and immobilizer unit, but also it can be clearly implemented in reality. So The invention in the industrial applicability.
